Syntax

Parameters

ForwardBufferMemory [in]

Size, in bytes, of the router packet queue used to store packet data. The default value is 74240 (fifty 1480-byte packets, rounded to a multiple of 256).

Return value

Returns a value of 0 (zero) for a successful completion when no reboot is required, 1 (one) for a successful completion when a reboot is required, and a different number if there is an error.
For more information on error codes, see WMI Error Constants or WbemErrorEnum. For general HRESULT values, see System Error Codes.

Remarks

When this buffer space is filled, the router begins discarding packets at random from its queue.

Packet queue data buffers are 256 bytes in length, so the value of the ForwardBufferMemory parameter should be a multiple of 256. Multiple buffers are chained together for larger packets. The IP header for a packet is stored separately. This parameter is ignored and no buffers are allocated if the IP router is not enabled. The buffer size can range from the network Maximum Transmission Unit (MTU) to a value smaller than 0xFFFFFFFF.
